Disposable utensil

Abstract

A disposable utensil is made from a cardboard blank and takes the form of a flat-bottomed hand scoop with forwardly sloped side walls, a back wall, and a pair of rear handles. The back wall is overlapped by a reinforcing wall which is in turn overlapped by a panel from which the handles extend and which is connected at the top to the back wall and at the bottom to the reinforcing wall.

Description

TECHNICAL FIELD

The present invention relates to a disposable utensil made from a cardboard blank and is intended for use, for example, in holding a slice of pizza while it is being eaten.

BACKGROUND ART

Hand holding and eating a slice of pizza can be a messy affair. The present invention aims to provide an inexpensive disposable utensil which can be conveniently used to serve a slice of pizza and hold it while it is being eaten. The invention is also applicable to serving and eating other food.

DISCLOSURE OF INVENTION

The preferred embodiment of the invention takes the form of a flat-bottomed hand scoop with a rear handle which can be slid under a pizza slice to capture it for eating. The pizza is then eaten by gently biting into the front of the slice, pulling the slice forward so that it projects partway beyond the utensil, and then biting off a piece of the projecting portion. In accordance with the present invention, the utensil is made from a die cut cardboard blank which is easily folded into the form of a scoop having a flat bottom wall, two forwardly sloped side walls, and a back wall. The back wall has locking tabs at its ends for interfitting with slots in the side walls and has a handle carrying extension panel which folds down at the rear. This extension panel has a pair of fold-out handles at its ends and a reinforcing panel at its rear which duplicates the back panel and also has locking tabs. The reinforcing panel doubles under the handle carrying panel to a position between the back panel and the handle carrying panel, and the tabs at the ends of the reinforcing panel overlap the locking tabs of the back panel and also extend through the slots in the side panels to interlock with the side panels. Thus erection is simple and the utensil is very inexpensive to produce.

BEST MODE FOR CARRYING OUT THE INVENTION

Referring to the layout of the blank for the utensil (FIG. 2), it is seen that the blank is symmetrical from left to right. Accordingly, the same identifying numerals will be applied to like cuts and fold lines on both sides of the longitudinal center line. The lower end of the blank, as appearing in FIG. 2, will hereinafter be designated as the front of the utensil.

Basically, the utensil has a rectangular base panel 10, a pair of side panels 11-12, a rectangular back panel 13, a rectangular reinforcing panel 14, a rectangular handle carrying panel 15, a pair of handles 16-17, two pairs of locking tabs 18-19 and 20-21, and a front lip 22. The blank for the utensil is die cut from a sheet of cardboard and indented to define four fold lines 23 through 26 outlining the base panel 10, four fold lines 26 through 29 outlining the handle carrying panel 15, a pair of fold lines 30-31 defining the side edges of the back panel 13, and a pair of fold lines 32-33 defining the side edges of the rear reinforcing panel 14. During the cutting operation, the following linear cut lines are made: cut lines 34-35 separating locking tabs 18-19 from the back edges of side panels 11-12, and cut lines 36-37 and 38-39 separating handles 16-17 from the back panel 13 and rear reinforcing panel 14. Also formed are gripping cutouts 34-35 in the handles 16-17 and locking slots 36-37 in the side panels 11-12. These slots have a straight portion 36a-37a which preferably terminates by a forwardly directed curved portion 36b-37b.

The two pairs of locking tabs 18-19 and 20-21 have the same shape; each tab is formed with a rounded hook portion at its free end having a beak 38 with a locking edge 39 defined by a V-shaped cutout 40 (see tab 18).

The handles 16-17 preferably have rounded outer edges 16a-17a and have their cutouts 34-35 of similar shape. These cutouts are preferably of a size adequate to receive a thumb and forefinger.

To assemble the utensil from the blank, the two side panels 11-12 and the back panel 13 are bent upwardly along the fold lines 23, 24 and 25, respectively. Then locking tabs 18-19 are folded forwardly in outer overlapping relation to side panels 11-12, and the beak portions 38 of the locking tabs are passed forwardly through the locking slots 36-37 to bring the apex of the cutouts 40 into registry with the upper ends of the slots 36-37. This makes a locking interfit between the beaks 38 of the tabs 18-19 and the portions of the side panels 11-12 between the upper ends of the slots 36-37 and the rear upper edge portions 11a-12a of the side panels. From these upper edge portions 11a-12a, the side panels preferably slope downwardly by sloped edge portions 11b-12b.

After the locking tabs 18-19 have been locked into position, the rear reinforcing panel 14 is folded downwardly along fold line 29 and doubled under handle carrying panel 15 and handles 16-17 so that the under face of panel 14 engages the under face of panel 15 and handles 16-17. Then the handle carrying panel 15 and underlying reinforcing panel 14 are folded down as a unit behind back panel 13. This locates the reinforcing panel 14 between the handle carrying panel 15 and the back panel 13, and positions the locking tabs 20-21 projecting laterally at the rear of the side panels 11-12. Next, the locking tabs 20-21 are bent forwardly along fold lines 32-33 and are inserted from the outside through the slots 36-37 in overlapping relation to the locking tabs 18-19 and into locking interfit with the side panels 11-12 in the same manner as previously described for locking tabs 18-19. Finally, the handles 16-17 are bent rearwardly at fold lines 26-27. The front lip 22 can be tilted downwardly along fold line 26 relative to the base panel 10 if desired.

An alternate erection procedure is to first double the reinforcing panel 14 beneath the handle carrying panel 15 and handles 16-17, and then fold panels 14-15 as a unit beneath the back panel 13. This locates the locking tabs 18-19 in overlapping relation to locking tabs 20-21. Then the side panels 11-12 are folded upwardly along fold lines 23-24; and the back panel 13, reinforcing panel 14 and handle carrying panel 15 are folded upwardly as a unit along fold line 25. This positions overlapping locking tabs 18-19 and 20-21 in laterally projecting position, and they then can be bent forwardly along fold lines 30-31 and 32-33 and inserted together through the locking slots 36-37.

The assembled utensil has the general appearance of a scoop with a pair of rearwardly extending handles. When used by a right-handed person, for example, the handles 16-17 may be gripped by bending the handles toward one another with the forefinger in cutout 34 and the thumb in cutout 35.

A rectangular cover 42 may be readily applied to the utensil after folding the handles 16-17 flat against the rear face of the reinforcing panel 14 and folding the lip 22 upwardly along fold line 26.

If desired, the fold lines 23-24 between the base panel 10 and the side panels 11-12 may diverge slightly from the back edge 25 of the base panel so that the utensils may be stacked after being formed from the blanks.

From the foregoing it will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without deviating from the spirit and scope of the invention. Accordingly, the invention is not limited except as by the appended claims.
